Bosch Oven Faulty Heating Elements
A Bosch oven not heating properly not means you have a dilemma to resolve, and most likely on an empty stomach. Fortunately, we can solve both problems ASAP with our Bosch oven troubleshooting guide. From a lack of power to a blown thermal fuse, we’ll pinpoint your Bosch oven heating problems.
HOW TO TROUBLESHOOT A BOSCH OVEN NOT HEATING PROPERLY
Whether it’s insufficient heat, unevenly cooked food, or no heat at all, a Bosch oven not heating properly feels like a worst-case scenario. However, many heating issues can have a simple and straightforward solution when you know where to begin. Our guide gives you the starting points you need to execute a fast fix.
#1 – No Power To Bosch Oven
When asking, “Why won’t my Bosch oven heat up?” sometimes the answer lies with your power source and not the oven. If your Bosch oven isn’t receiving power, it won’t be able to provide heat. Here’s how to check your power sources to make sure your oven has adequate electricity:
- Make sure your oven is properly plugged in.
- Refrain from using an extension cord with your oven, as most cords can’t safely transmit the electricity an oven requires.
- Check your circuit breaker for blown fuses or tripped breakers, especially if you experience a power outage.
#2 – Bosch Oven Clock Reset
After a power outage the clock on your oven will revert to its factory setting and flash “00:00.” Your Bosch oven will not operate until you reset the clock’s time and “00:00” is no longer flashing.
#3 – Bosch Oven Not Calibrated Correctly
If you’re dealing with long cooking times, undercooked food, or food that’s not cooked evenly, it’s possible the oven thermostat needs recalibrating. Recalibrating your oven can better enable the temperature setting to match the oven’s internal temperature and facilitates more accurate cooking times.
Most ovens can be recalibrated in increments of 35°F at a time via your control panel. Check your owner’s manual for the exact calibration steps for your model oven. If recalibrating doesn’t fix your Bosch oven not heating up, there’s a small chance your oven thermostat is faulty and requires replacement.
#4 – Blown Oven Thermal Fuse
The thermal fuse on your Bosch oven is a protective feature that prevents the oven from overheating. The thermal fuse will blow if the oven gets too hot, cutting power to the oven and forcing it to cool down.
An oven’s thermal fuse can blow when exposed to the high temperatures of a self-cleaning cycle. To prevent this occurrence, the best way to clean an oven avoids the self-cleaning feature altogether. A thermal fuse can also blow if the fuse is faulty. In either case, if multimeter testing reveals a lack of continuity, the fuse must be replaced.
#5 – Oven Component Malfunction
If these troubleshooting tips still leave you with a Bosch oven not heating properly or that leaves food unevenly cooked, it’s possible a broken part is to blame. These components can leave you with heating problems when they malfunction:
- Heating elements: The heating elements at the top and bottom of an electric oven work together to create even heating, while the top element also broils food. If one of these elements breaks or malfunctions your oven won’t heat up properly or not heat up at all. Heating element malfunctions are diagnosable by a lack of continuity. You may also notice visible damage or a lack of red glow in the heating element.
- Convection motor: Convection ovens use a fan to circulate heat throughout the oven’s interior, resulting in more even heating and faster cooking. If the motor that powers the fan malfunctions, the fan won’t operate and the oven’s air won’t circulate, resulting in improper heating.
In either instance, these components cannot be repaired and require replacement. We recommend professional service for these complex repairs.Schedule Appointment
